Norton Internet Security blocking execution of scripts loaded via XMLHtppRequest

Has anyone else seen this?  Norton Internet Security seems to be
blocking execution of same-site script tags loaded via XMLHtppRequest.

I know there are at least two other common methods for loading scripts
dynamically, but for simplicity and speed I have been embedding them
into the html returned via calls to XMLHttpRequest for some clients'
"AJAX" projects.

Suddenly, I have found that Norton Internet Security is aborting the
main Javascript routine (not the dynamically loaded scripts) without
an error message of any sort.  Processing just stops when the
following function executes:

AjaxBase.prototype.executeScripts = function(html) {
   // can't find a regexp that finds complete script tags in FF 1.5!
   // so, do it brute force:
   var reFindStart = new RegExp("<script.*?>", "im");
   var strFindEnd = "</script";
   var scripts = html.split(reFindStart);
   for (var i = 0; i < (scripts ? scripts.length : 0); i++) {
     var end = scripts[i].indexOf(strFindEnd);
     if (end > 0) {
       var script = scripts[i].substr(0, end);
       eval(script);
     }
   }
}

Again, the html was retrieved from the same site as the main page.  The
HTML is returned fine.  This is the script tag that is being returned in
the html:

<script type="text/javascript">
window.homeValue = {"HvbLowValue":581600,"HvbHiValue":666400};
window.homeAddress = {"Address1":"41 Some
Rd","Address2":null,"City":"Somewhere","State":"MA","Zip":"01801-0030"}
</script>
Any ideas?
